Y zen of the United States, residing at ABoston,

in the county of Suffolk andState' of Massachusetts, haveinvented newand useful Inn provementsI in" lVater-Gages'f, of which the,

o llowing is a specification.

This invention relates to'wate1-gages for application to steam boilers,and it consists in a new and improved construction and combination ofarts whereby the passages in one onmore e the water-glasses employed maybe cleared and sediment removed there; from and from the passagesleading thereto `by blowing the water up lthrough the glass as wellasblowing the sf-eariildown; whereby bubbles which are aptlto forinin theglasses when the boiler -ispriming'ior foaming and for various causes,thus interfering-with the accuracy of the indication of the watertherein, are prevented fromentering the glasses ;A wherebyT a safely oerating'glass is provided in connection witli 'which the steam andwater-valves can be run fully o en; whereby the operatorie able-Itoclose eit er the steam or watervalves without Abeing-wet or scalded whenone or more oftheiwaterfglasses are broken, bydiverting,currents: ofsteam and water from the broken glass; and whereby is rendered moreeli'cient in operation. u

Thelower end ol' the portion 36 is provided with an internal ilange 43 overwhich is the lower end of the glass 447 and said fiange 43 constitutes aseat for a valve 45 whose stein 46 is screwed into an internallythreaded nut` 47 provided with ailange 48 Whichbears againstthe lowerend of the portion 35 of the base into whichv it screws, and is alsoprovided .with a suitable cap or stuifing-box 49. The parts abovementioned from 36 to 49 inclusive are the saine at op iosvite ends ofthe base, and each ol' the .metallic tubes 39 is provided with the usualopposite vertical slots or openings 50 constituting windows. The shapeof the lower end of each tube is well illustrated in.y Figs. 1 and 6, inwhich it appears that the slots or windows 56 are somewhat narrowedtroni and below the upper end oi' the threaded portion 3S and thenceextend down to the point 51 .(Fig. 6) below which the tube 39 is wholeand unslotted. On the bottoni ot' the slot ol' each tube rest oppositeguides or lugs 53 ol' two halves ol' a divided gland 52, see Figs. 1, 4,5, l6 and 7. The curved portions 52 ot' these glands iit slidingly inthe metallic tube 39 and around the glass tube 44 and rest upon thepacking 54, as illustrated in Fig. 5 (this acking is omitted in Fig. 6).The guides or lugs 53 of the two halves extend into the slots 50, two,lugs extending into each slot, and thc nut 42 .is adapted to press downthe lugs 53 and thus force the divided gland down on the packing 54around each glass. The upper end of each tube 39 is provided withreversely laced parts similar to those described at the Owerf'end ol'the tube viz., a nut 55 on the. .upper threaded end 56 ol' the tube 39'correondin with the nut 42 on the lower t reade end 33, glands providedwith lugs 57 extending into the upper narrowed end ot' the slot 50 corrasponding with the glands 52, 53, and a nut 58 corresponding-with thenut 36, 37. The nut 41 at the lower end is not d uplieated at the u pperend. Connected by suitable unions 59 with the upper ends ot the tubes39next the upper' ends olthe glasses 44 are steam-pipes 6() which connectsaid glasses by fneans olsuitable unions 6l with tbc out- Wardlyextendinghorizontal tul)ularbranches 62 integral with a structurecompris-ing said branches, a downwardly exti'rnding branch 63 andupwardly diverging branches 64 which are provided at their lower endswith vulveseats for valves 66 whose stcnis 67 are threaded at 63 l'orengagement with nuts 69 suit'abhv packed at 76A it will be seen byreference to Fig. 2 that the lower portions of the paris 64- arcconnected with the horizontal pipes 62, and thi` passages in thevalve-seats 65 open into the upper end of the pipe 63, all as indicatedin liigs. l, 2 and 3. The lower ond ot the pipi` 63 is united by aconnection 71 with the ccntra-l glolm-sha )ed casing 72 t'orincd withopposite integral tubular horizontal extensions 73 and 74 and providedat its rear side with a valveseat 75 which connects with the stcanipipe17 (Figs. 3 and 9) said scat being for tho valve 76 whose stein 77 isthreaded at 7S tor engagement, with a nut 79 suitably' packed at 80. Apartition 81 extends troni thc upper portion of' the wall ot tht` part72 next the cxtension 73 downward substantially diagonally and intotthecentral portion ol" the cx tension 74, as shown in Figs. 2 and 3. Thebubble-pipe 28 (above mentioned) connects the base at 27 with theextension 73 b v Ineans of a suital'ile union 82. Sec Figs. l, 2 and 5.Connected by a suitable union s3 with the opposite extension 74 is ablow-ott pipe S4 provided with a suitable valve 35 and opening at itslower ond into tin` blow-oil' pipe i5 below the valve i6.

ln operation, thc stcain enters thil glasses through the stcanispipc 17,thc wilvc-chain lzer within the case 72, around the edge o' thcpartition S1, up through the connection 7i, pipe 63 and the passages intbc valve-s ats 65 through the lower portions ot the chainbcrs inthediverging branches 64 into thc opposite branch-pipes.62, and thencethrough tln` pipes 6t)\into the upper cnds of tlu.` glasses ltftit beinguinlcrstood that thel main valvr` 76, 77, and th(` twin di'vcrgingvalves 66, 6T are open. As thc divcrging valve-.mochauisins 66, 67, 69ar(` entirely independent ol' cach other, it is evident that by leavingone closed the steam can onlycntcr one ol' thc glasses. llcncc it citherglass is broken or out of condition the other glass can be used, as thi`ports in the va-hfc-scats 65 open into a. passage con'nnon to both.

As

air bubbles vmust necessarily rise they, after entering the chamberZOthrough the waterpipe' l, cannot passldowninto and through the passage33 `whoseoutlet is so far below' the passages 8l, but must rise throughthi` coupling` 2'7 into the bubble-pipe 28 and pass through it into thepipe v73 and thence linto i the valve-chamber in `the casing 7 2,' andthence they are free to pass through the passage inthevalVe-seat (thevalve 76 being Withdrawn therefrom) and through the steam-pipe 17 tothe'water-eolunm. Thus they are prevented by the funnel-shaped par#tition 30 from entering the passages 31 and reaching the Water-glassesBy means of this invention it is possible 'for thc-purpose of cleaningout the glasses -and other passages not only to blow steam 'down throu,Vh 'the passages but to blow the Water up t rough then'i. To blow steamdown, the valve 21, 22 is Closed, the valve 29 in the blow-oil"connecting. pipe 26 is opehed as are also thevalve 76, 77, the valves66, 67, and the` valves 45, 46. The steam passes therefore through thepipe 17, the chamber in the valvecasing 72, the pipes 7l and 63, the'lpassages in the Valve-seats 65,' the passages lin the lower ends of the'casings 64the, pipes 62 and the pipes 6() to the glasses, ahd alsothrough the pipe 73 into the bubble-pipe 8 and down through it and thepipe 27 into the chamber 2O and thence down through the pipe 26 into theblow-oil' pipe 15.

lll() To force water up for the purpose olly-lean# i ingthe glasses andpassages, the valves`29 and 76, 77 are closed and the valve 2l 22 isopened, asis also the valve in the blow-oil' connecting pipe 84. TheWater passes` through the pipe )S into the chamber 20,. and tl'ience aportion passes up through the pipe 27,-the bubble-pipe 28 and pipe 73into the if'alVc-chauiber in the portion 72, and thenci` under the edgeof thepartition 81 into the blow-oil connecting pipell which conducts itto the blow-oli pipe 1'5, and a portion o f fthe .water passes from. thechamber 2() ithr'ou'gl'ithe passage up through the pas? sagesl 31 andthrough1 the passages in the"` ifpalvefseats 43 `(the` v'altfes 45beingr open) i" to thegfl'asscs, and thence through the pipes' .60 and'62 down through'fthe pipesv 63 and '7l' into.thevalve-clraniber in thelcase 7i?, and

as resting'on the flanges 43. ln' practice thence over the pentiti-onSlinto the blowthey may or may not rest on these flanges,

and in l'act it is usually better' that they should bc somewhat. raisedtherefrom for the reason that it is ol'tcn necessary to rotate the ltubes I() in order that the windows or slots therein may tace in adesired direction, such rotation producingr rotation of the glasses i4by means ol' thc packing 54. When the tubes CSS) have been rotated tothe desired point the nuts l1 (which have been loosened to allow suchrotationl are turned down on the upper edges of the portions 37 of thenuts beneath them, and the tubes are thus held at the desired pointsupporting the glasses usually at a somewhat raised position from theflanges 43.

1t is evident that as the operator can divert the currents ol steam andwater from a broken glass to the blow-oli pipe while he is at a distancefrom the water-gage, the danger of becoming wet or scalded by reason ofan accident of this nature is obviated, i

In Fig. S a detail is shown'in which the )rinciple involved in theimproved base is illustrated as applied to a water-gage having a singleglass. s4, the lower portion 38 of the slotted tube 39, glands 52, nuts42 and 41, and nut 37, v110, and 36 are constructed as in the otherfigures in the drawing. The flange 43 of the. lastnamed nut has integralwith it a downwardly extending tube or outlet :SG which extends into theportion S7 of the base and opens directly over a downwardly extendingtube SS which corresponds to the tube 24 in the other iigures. Thisportion S7 ol' the base constitutes a wing corresponding to the portion34, 35 at one end of the base in the other ligures and this wing isconnected bythe part S9 provided with passage to the niain portion. 9].ln this construction the water enters the chainbcr 92 in the mainportion Ell and passes through the passage 9() and up through thedownwardly extending tube S6 whose mouth is below thc passage JO as themouth ol the passage 33 is below the passages 3l in Fig. 5, so thatbubbles cannot cnter the glass. The blowing-oill operates substantiallythe sanie in Fig. S as in thc other ligurcs, the valve-stem 93corresponding to thc Valve-stem 22, and the pipe lli corresponding tothe pipe 27.
